ADVERTISING DEVICE.

SPECIFICATION forming part of Letters Patent No. 485,676, dated November8, 1892.

Application filed December 7, 1891. $eria1No. 414,332. (No model.)

To all whom it may concern.-

Be it known that we, JAMES A. WRIGHT and JOHN B. WRIGHT, citizens of theUnited States, residing at Rockingham,in the countyof Richmond and Stateof North Carolina, have invented a new and useful Advertising Device, ofwhich the following is a specification.

This invention relates to advertising, and more especially to that classthereof known as picture-exhibitors, and the object of the same is toproduce certain improvements in devices of this character.

To this end the invention consists in a machine embodying theconstruction hereinafter more fully described and claimed, and asillustrated on the two accompanying sheets of drawings, wherein-- Figure1 is a general perspective view of this improved machine with thetreadle located in'the sidewalk and the standard and frame at one sidethereof. Fig. 2 is a vertical section on the line 2 2 with the rightside of the standard removed. Fig. 3 is an enlarged central verticalsection of the upper portion of the standard, showing in outline wherewe locate a magic lantern and omitting the frame. Fig. 4 is an enlargedperspective detail of the ratchet-wheel partly in section to show itsconstruction. Fig. 5 is an enlarged elevation of the brake mechanism,showing the bell as connected therewith. Fig. 6 is an inside elevationof the frame. Fig. 7is a cross-section thereof on the line 7 7 of Fig.6.

Referring to the said drawings, 1 designates the sidewalk having a hole2, within which fits loosely a platform or treadle 3.

4 4 are rock-shafts journaled in bearings beneath the sidewalk ateachtransverse side of said hole, and 6 are arms projecting horizontallyfrom the shafts to one side thereof and having turned-up ends 7, whichsupport the treadle, depending levers 8 from said shafts being connectedby a wire or chain 9, which leads inwardly beneath the platform andsidewalk toward the building.

10 is a spring connected with one or both of the levers and holding theplatform normally raised, and 11 are stops and limiting the downwardmovement of the platform, so as to prevent a too-great depressionthereof.

12 is a bell-crank lever pivoted in a bracket 13, the chain 9 beingconnected with one arm of the lever and a vertical chain 14 leading upfrom the other arm thereof.

designates a standard or casing of rectangular horizontal section andmounted on or rising from the sidewalk or secured to a building at suchpoint that the vertical chain 14 rises inside the standard.

21 is a short lever pivoted at one end 22, connected between its ends tothe chain 14, and connected at its other end by a chain or cord 23,which leads upwardly in the standard over a ratchet-wheel 30, beingconnected to a pin 24 in the periphery thereof, and thence extendingdown to a coiled contractile spring 25, which is attached at its lowerend 26, to a partition 27,which stands transversly across the standard.

The ratchet-wheel is journaled loosely upon the right end of ahorizontal shaft 31, the latter being provided with oppositely-disposednotches 32, and 33 is a pawl sliding within the body of the wheel andthrown normally into the notch beneaththe tip by a' spring 34, all asbest seen in Fig. 4. The shaft 31 is journaled in the partition 27, andat the left side of the standard between said journals it is providedwith a large flat wing '35, and adjacent its left bearing it is slightlyflattened, as at 36. Over said wing passes an endless apron 38, of clothor other fabric, and 39 are cards independently connected to the outerface of the apron, the vertical width of each card being equal to thewidth of said wing.

The brake mechanism, (best seen in Fig. 5,) comprises a bar 40, pivotedat 41 at one end to the left side of the standard, bearing at its centeron the slightly-flattened portion 36, and connected, as at 42, to achain, which leads downward to a contractile spring 43, secured at itslower end 44 to the casing.

45 designates merely in outline a gong or bell of any approved patternor construction, which is connected with the chain, so that when thebrake-bar rises the bell will be sounded, although we reserve the rightto apply this bell to any other preferred part of the machine or to omitit entirely if we desire.

The frame 50, best seen in Figs. 6 and 7, has the rear faces of itsvertical side bars beveled, as at 51, and its top bar provided withbeveled notches 51. 52 are vertical bars located in the frame andgrooved on their adjacent faces, so as to receive vertical strips 53 ofcard-board or the like, which are inserted in the upper ends of thegrooves through the notches 51'.

54 are horizontal strips connecting the two inner vertical strips witheach other and the two outer vertical strips with the side bars of theframe, and 55 are short horizontal cards inserted between the groovedadjacent edges of the horizontal strips, the outer cards being insertedat the outer ends of the grooves by reason of said bevel 51 and theinner cards being inserted by means of a bevel 52' on the rear face ofone of the vertical strips. The front of the casing 20 is omitted fromthe line 28 to the upper end thereof, and a pin 29 rises from the end ofthis front. The frame above described closes the open front of thecasing, the pin 29 entering a hole 56 in the lower cross-bar of theframe, and hooks 57 011 the rear sides of the inner vertical strips ofthe frame take into holes 58 in the upper end of the standard. By thismeans the frame is detach-ably connected to the standard and closes theopening in front thereof; but when one or more of the center tier ofcards are withdrawn an equal number of the cards 39 of the endlessseries will be exposed through the openings in the frame.

Every time a pedestrian passing this device steps on the platform ortreadle he operates the rock-shafts, draws on the chain, turns theratchet-wheel, moves its shaft one-half revolution and thereby carriesthe cards one space upward, the movement of this shaft op erating thebrake-mechanism and sounding an alarm on the bell, whereby attention iscalled to the advertising device and to whatever reading, pictorial, orother matter may be placed on the stationary cards as well as those ofthe endless series, as many of the latter being exposed as there are ofthe former withdrawn from the vertical tier. The frame by its specificconstruction is adapted to be removed from the standard when it isdesired to change the cards, and the peculiar bevels above describedpermit the cards to be very easily withdrawn and inserted. The devicecan be made of any size and materials, and we preferably employ thoseabove indicated; but in some cases the cards 35 may be replaced byground glass strips having signs or inscriptions printed thereon, and areflector or magic lantern, as designated in outline by the letter M,may be suitably supported with in the standard, so as to throw the signsor inscriptions greatly magnified onto the sidewalk, the building acrossthe way, a sheet, or a suitable screen of any kind, and this construction can be used to advantage in connection with the treadle andoperating devices above set forth.

What is claimed as new is- 1. An advertising-frame having the rear facesof its side bars beveled and beveled notches in the rear face of itsupper cross-bar, vertical strips in said frame having their oppositefaces grooved and arranged in pairs beneath the edges of said notches,one of said strips having a beveled rear face, horizontal grooved stripsconnecting the outer vertical strips with the side bars and the innervertical strips with each other, the grooves opening in line with thebevels on the side bars and on said vertical strips, and pieces ofcardboard removably located in said grooves, as and for the purpose setforth.

2. In a device of the character described, the combination, with atreadle or platform located in a hole in the sidewalk, rock-shaftsjournaled below said platform and having projecting arms supporting. it,depending 1evers from the shafts, and a spring bearing one of saidlevers in a direction to hold the plat form normally raised, of anupright standard, a shaft journaled across the upper end there of, andconnections between said treadle and shaft for causing the latter toturn intermittently when the former is depressed, brake mechanism forpreventing a retrograde movement of the shaft,- and an endless series ofad vertising-panels mounted on said shaft and by the motion thereofsuccessively exposed through an opening in the front of said standard,substantially as described.

3. In a device of the character described, the combination, with atreadle, an upright standard having its front cut away and having avertical partition, a lever pivoted at one end to the partition, and achain connecting the treadle with the lever between its ends, of a shaftjournaled through the partition and one side of the standard and havingnotches, a ratchet-wheel journaled on the shaft and having aspring-actuated pawl engaging said notches, a chain leading from theother end of said lever around the wheel to a contractile spring,endless series of advertising-panels mounted on said shaft and by themotion thereof successively exposed through said cut-away portion, andretaining devices for said shaft, substantially as described.

i. In a device of the character described, the combination, with anupright standard having an opening in its face, a horizontal shaftacross the standard near the upper end of said opening, and means forturning the shaft intermittently in one direction, the latter beingflattened near one journal, of a series of advertising-panelssuccessively exposed through said opening, a lever pivoted at one end tothe standard and bearing between its ends on said flattened portion, achain leading from the other end of the lever to a contractile spring,and a bell connected with the chain, substantially as hereinbeforedescribed.
